RISImproving the Accuracy of Dynamic Modulus Master Curves of Asphalt Mixtures Constructed Using Uniaxial Compressive Creep Tests
Publisher: American Society of Civil Engineers
Abstract: Uniaxial monotonic or constant loading tests have been used to efficiently construct master curves of the magnitude and phase angle of the complex modulus of asphalt mixtures. However, when using monotonic or constant ...

Improved Method of Characterizing Fracture Resistance of Asphalt Mixtures Using Modified Paris’ Law: Development of Methodology
Publisher: ASCE
Abstract: It is crucial to accurately determine the coefficients of the modified Paris’ law to accurately characterize the fracture properties of an asphalt mixture. However, the current methods reported in the literature are ...
Development of Two-Phase Diffusion Model Consisting of Free and Bound Water Molecules for Water Vapor Diffusing into Asphalt Mixtures
Publisher: ASCE
Abstract: Water vapor diffusing inside asphalt mixtures is one of the most important ways for water molecules accessing asphalt mixtures to trigger moisture damage. Several diffusion models have been constructed to describe the water ...
Quantitative Analysis Investigation of the Water Stability of Asphalt Mixtures with Crushed Gravel Based on the Theory of Surface Free Energy
Publisher: ASCE
Abstract: To quantitatively analyze and study the water stability of crushed gravel asphalt mixture by using surface energy theory, the surface energy parameters of crushed gravel samples at 20°C are tested by using the gas sorption ...
Influence of Infiltration Velocity on the Measurement of the Surface Energy Components of Asphalt Binders Using the Wilhelmy Plate Method
Publisher: ASCE
Abstract: Two common test methods measure the surface energy of asphalt binders: the Wilhelmy plate method and the sessile drop method. In contrast to the sessile drop method, the Wilhelmy plate method introduces the influence of ...
Selective Absorption of Asphalt Binder by Limestone Aggregates in Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: It has been found that aggregates used in paving asphalt mixtures absorb the asphalt binder into the porous structure of the aggregates. National test methods are available to measure the aggregate absorption. However, ...
Self-Consistent Micromechanics Models of an Asphalt Mixture
Publisher: American Society of Civil Engineers
Abstract: An asphalt mixture is a composite material consisting of three components: asphalt binder, aggregate, and air. The mechanical properties of asphalt mixtures are mostly evaluated from empirical approaches that are usually ...
Characterization of the Tensile Viscoelastic Properties of an Undamaged Asphalt Mixture
Publisher: American Society of Civil Engineers
Abstract: All characterization of asphalt mixtures must begin with the properties of the mixture in an undamaged state. Subsequent tests of the mixture in different stress or strain states at a level to cause damage can be referred ...
Characterization of Asphalt Mixtures Using Controlled-Strain Repeated Direct Tension Test
Publisher: American Society of Civil Engineers
Abstract: A controlled-strain repeated direction tension (RDT) test is useful for characterizing asphalt mixtures and assessing fatigue cracking accompanied by plastic deformation. The strain curve in a loading cycle of the ...
